This gives a new definition to being a switch hitter.

Steroid-addled former baseball All-Star José Canseco is accused of backing out of a Celeb rity Boxing tournament over the weekend and secretly sending his twin brother, Ozzie, as his replacement — hoping that no one would be wiser.

Instead, his twin, also a body builder, showed up, and the fight was canceled.

Now José Canseco, who hit 426 career home runs, and Celeb rity Boxing CEO Damon Feldman are accusing each other of trying to deceive the fans with the switche roo.

“To make a long story short, Damon tried, at the last sec ond, tried to an nounce my brother, Ozzie, was José Can seco,” a man purporting to be Canseco told The Post via telephone. “The last thing my brother wanted was to commit fraud. Damon tried to pull a fast one.”

The Post called a special $1.99 toll telephone number Canseco posted to his Twitter page, where he said he’d give his side of the bizarre chain of events.

Canseco, 46, said that he’d thrown out his back and was in no shape to fight but that Feldman approved Ozzie, who had a stint as a pro ballplayer himself, as a replacement.

He says that the deal was that Ozzie would portray José for the prefight publicity pictures but that when it came to fight time, Ozzie would fight under his own name.

And the brothers would split Canseco’s $10,000 fee.

But Feldman, who pleaded no contest to fight fixing and promoting fights with a license in Pennsylvania earlier this month, has a different version of events.

“We discovered the Canseco who showed up was Ozzie when he took off his shirt and [he] didn’t have José’s tattoos on the biceps that appear in our advertising,” a Celebrity Boxing spokesperson told The Miami Herald.

José Canseco scandalized baseball in 2005 with his tell-all account of steroid use in the major leagues.
